TSS4550

IrDA – UART Integrated Interface

Description

The TSS4550 is a very low power consumption

integrated circuit. It combines the functions of a

PC–compatible UART and an IrDA interface circuit. It

provides both serial and infrared communication

interface ports to a processor. It connects to an external

bus which may be either multiplexed address/data bus or

separate address and data buses. It incorporates a

FIFO–buffered high speed UART. The output of the

UART may be connected, using a 3 way multiplexer, to

either an external IrDA transceiver via an internal pulse

shaping circuit or directly to one of two separate

MODEM compatible output ports (logic levels). The

pulse shaper is compliant to the IrDA standards

revision 1.2.

The TSS4550 also provides additional peripheral

support by way of control outputs and a parallel I/O port.

In addition to normal operating modes, the device has a

power–down mode for power saving and test modes to

assist with board manufacturing.
